I COMPOSITION FOR USE IN FINISHING TEXTILE MATERIALS.

Io Drawing.

county of Lancaster, England, have in-' vented certain new and useful Compositions for Use in Finishing Textile Materials, of which the following is a specification.

This invention relates to an improved process of treating textile materials.

' The invention relatesto the operations which are performed on materials such as yarns or fabrics after the spinning or weaving and are commonl embraced within the expression finishing processes. These finishing processes may include sizing, filling or loading or the like, which processes are intended to improve the appearance and or strength of the material and to give them special properties. One of the objects of the present invention is to provide an improved finishing process for textile materials.

The invention consists in applying in conjunction with the usual finishing agent, colloidal silica or a colloidal silicate especiallyy the colloidal clayknown as bentonite. The colloidal silicate especially bentonite, may be applied for example, to fabrics after such fabrics have been washed with soap-alone or with soap and bentonite or'with my improved bentonite detergent composition described in my application Serial No. 610,911. Soap alone is commonly used as afinishing agent for materials which have been scoured either with soap or with my improved bentonite composition and the present invention includes the use of soap in conjunction with colloidal silica or bentonite or other colloidal silicate. I

In certain finishing processes a quantity of the finishing agent (e. g. the soap agglutinant or filler such as china clay) remains in the fabric and in the present process a small quantity of the colloidal silicate also appears to remain therewith and confers valu- Application filed August 25, 1924.

able improved properties upon the material.

Finishing materials like Glaubers salts, magnesium sulphate, or china clay can be used and may be dispersed in the colloidal silicate. On drying the finishing agent is retained in the material and dusting of the fibre does not occur.

The result depends upon the fact that the bentonite or the like has a very highly marked power of adsorbing materials and of being adsorbed by the fabrics or the like.

The colloidal silicate is most suitably employed at the same time as the other finishing agents but-it may be used immediately before-or immediately after the other finish ing .agents or may be applied more than once or be used alone. I do notrinclude the use of colloidal silicates in processes in which scouring takes place. The following is an example of one manner in which my invention may be carried out.

Ewan agile.

Filling of cotton piece g0ods.-Cotton piece goods which require to be filled are passed through a mixture containing 15% of bentonite together with china clay, Epsom salts, starch or other usual filling materials; The material being applied by the usual mechanical devices employed.

In my invention I do not make or use'adhesives but I treat textile materials with compositions as defined in the claims.

I declare that what I claims is:

1. A composition for use in finishing textile materials containing bentonite and a sulphate having a neutral re-action.

' 2. A composition for use in finishing textile materials containing bentonite and Epsom salts. v

- In witness whereof, I have hereunto signed my name this 12th day of August 1924.
